Since the question says "everyone" away.. I'd lean towards Avoidant attachment issues. AKA fear of getting too close or hurt. Some people can't accept love or feel they lose control or their independence. I'm sure it's nuanced.

Fear, unwillingness to heal, and trust again. Mostly their reasons are all internal and could be remedied if they took the steps to kove forward in healthy ways. Most don't because it's too hard.

Joke and assume all you want people, but there's a reason and it doesn't involve blaming the person who is afraid.

If life hasn't been kind to one, general distrust due to fear of being hurt again can be a major reason.

I couldn't tell you 🤷🏻
